​​From the beginning, Discord has been an early adopter of Elixir. The Erlang VM was the perfect candidate for the highly concurrent, real-time system we were aiming to build. We developed the original prototype of Discord in Elixir; that became the foundation of our infrastructure today. Elixir’s promise was simple: access the power of the Erlang VM through a much more modern and user-friendly language and toolset.

​​In our life as X-Ops — i.e. roles like DevOps, CloudOps, GitOps, SysOps — we focus on building infra-as-code. We frequently use Docker to build and test, commit and pull the code to/from repositories, and when all tests pass, infra moves in production — completely automated.

​​I’ve been working in DevOps for a while now, and I’ve yet to come across a tool that didn’t have something odd about its name. It’s either got a backstory, a meaning, or it’s Greek. I don’t know why, but I’d postulate that it’s because the market is completely flooded with tools, and you need yours to stand out, so you can make money — either from the tool itself, or a support package.

​​Last week, I found myself caught in the firing range of functional programmers — all because I dared put forward an alternative mode of thinking for JavaScript. This is probably also the first time I’ve ever gotten hate and love mail, public condemnation, accolades and tweets for something that had innocent intentions and origins. Somehow, I also managed to get myself labeled a purist, among other things.

​​I know there are plenty of places online (StackOverflow, MDN) that can be an excellent resource for exploring loops and Array iterable methods. But… sometimes it’s good to write about something just so that these patterns settle in your mind and the knowledge is cemented for good. As a result, I found some things I didn’t know existed. In this article I’ll share them with anyone who needs to get a better insight into loops!

​​Today most of the legacy backend systems are based on the REST(REpresentational State Transfer), but from the last 2–3 years “Graph QL” AKA replacement for REST, a new way to serve data is getting popular. So what is it, why to use it and how to use it, we will discuss all about GrapQL .

​​At mitter.io, we have a couple of public-facing npm packages that we need to publish, and we recently moved to a mono-repo structure managed by Lerna from having separate repositories for each one of them. Today, I’d like to share our experience of this migration and our setup with the new monorepo structure.

​​As part of my personal journey to gain a better understanding of Deep Learning, I’ve decided to build a Neural Network from scratch without a deep learning library like TensorFlow. I believe that understanding the inner workings of a Neural Network is important to any aspiring Data Scientist.

​​You can write Python programs to interact with the file system to do cool stuff. How to do so isn’t always super clear.

​​A few months ago I joined Halo Labs to help build our AR/VR design and prototyping platform. After the first interview, I received a “take home” exercise, to build a simple VR scene. While I was excited to build a VR app for the first time, I was also a bit afraid. I’m coming from a web development background and I never worked on a VR project before. To my surprise, it took me roughly three hours to finish the exercise, and it even looked pretty good (well, at least to me…).

​​RESTful is not a new term. It refers to an architectural style where web services receive and send data from and to client apps. The goal of these applications is to centralize data that different client apps will use.

​​Recently I’ve adopted a new philosophy that changes the way I make components. It’s not necessarily a new idea but rather a subtle new way of thinking.

​​One of Javascript’s many quirks is something known as hoisting.

Now if you are new to coding in Javascript, it’s quite likely that you’re not writing your code perfectly just yet. So because of this, it’s highly likely that your hoisting isn’t perfect either. 😉

​​I hate CSS. Well, I hated CSS. While learning to write code, CSS seemed like an inoperable black box. The twin tasks of deciding how something should look, and then making it look that way seemed just impossible. Which resulted, very naturally, in a deep-seated hatred of the entire art.

​​JavaScript fatigue has become a common phrase in the world of today’s front-end developers. It can seem like there’s a new hyped framework, architecture, command line tool, or SaaS developer service every day. The constant churn of new things can end up leaving developers more jaded than excited.
